Embodiments of the present invention provide methods, compounds, and compositions for reducing expression of Factor 7 mRNA and protein in an animal. Such methods, compounds, and compositions are useful to treat, prevent, or ameliorate thromboembolic complications, hyperproliferative disorders, and inflammatory conditions.
The circulatory system requires mechanisms that prevent blood loss, as well as those that counteract inappropriate intravascular obstructions. Generally, coagulation comprises a cascade of reactions culminating in the conversion of soluble fibrinogen to an insoluble fibrin gel. The steps of the cascade involve the conversion of an inactive zymogen to an activated enzyme. The active enzyme then catalyzes the next step in the cascade.
Coagulation Cascade
The coagulation cascade may be initiated through two branches, the tissue factor pathway (also “extrinsic pathway”), which is the primary pathway, and the contact activation pathway (also “intrinsic pathway”).
The tissue factor pathway is initiated by the cell surface receptor tissue factor (TF, also referred to as factor III), which is expressed constitutively by extravascular cells (pericytes, cardiomyocytes, smooth muscle cells, and keratinocytes) and expressed by vascular monocytes and endothelial cells upon induction by inflammatory cytokines or endotoxin. (Drake et al., Am J Pathol 1989, 134:1087-1097). TF is the high affinity cellular receptor for coagulation factor VIIa, a serine protease. In the absence of TF, VIIa has very low catalytic activity, and binding to TF is necessary to render VIIa functional through an allosteric mechanism. (Drake et al., Am J Pathol 1989, 134:1087-1097). The TF-VIIa complex activates factor X to Xa. Xa in turn associates with its co-factor factor Va into a prothrombinase complex which in turn activates prothrombin, (also known as factor II or factor 2) to thrombin (also known as factor IIa, or factor 2a). Thrombin activates platelets, converts fibrinogen to fibrin and promotes fibrin cross-linking by activating factor XIII, thus forming a stable plug at sites where TF is exposed on extravascular cells. In addition, thrombin reinforces the coagulation cascade response by activating factors V and VIII.
The contact activation pathway is triggered by activation of factor XII to XIIa. Factor XIIa converts XI to XIa, and XIa converts IX to IXa. IXa associates with its cofactor VIIIa to convert X to Xa. The two pathways converge at this point as factor Xa associates factor Va to activate prothrombin (factor II) to thrombin (factor IIa).
Inhibition of Coagulation
At least three mechanisms keep the coagulation cascade in check, namely the action of activated protein C, antithrombin, and tissue factor pathway inhibitor. Activated protein C is a serine protease that degrades cofactors Va and VIIIa. Protein C is activated by thrombin with thrombomodulin, and requires coenzyme Protein S to function. Antithrombin is a serine protease inhibitor (serpin) that inhibits serine proteases: thrombin, Xa, XIIa, XIa and IXa. Tissue factor pathway inhibitor inhibits the action of Xa and the TF-VIIa complex. (Schwartz A L et al., Trends Cardiovasc Med. 1997; 7:234-239.)
Disease
Thrombosis is the pathological development of blood clots, and an embolism occurs when a blood clot migrates to another part of the body and interferes with organ function. Thromboembolism may cause conditions such as deep vein thrombosis, pulmonary embolism, myocardial infarction, and stroke. Significantly, thromboembolism is a major cause of morbidity affecting over 2 million Americans every year. (Adcock et al. American Journal of Clinical Pathology. 1997; 108:434-49). While most cases of thrombosis are due to acquired extrinsic problems, for example, surgery, cancer, immobility, some cases are due to a genetic predisposition, for example, antiphospholipid syndrome and the autosomal dominant condition, Factor V Leiden. (Bertina R M et al. Nature 1994; 369:64-67.)
Treatment
The most commonly used anticoagulants, warfarin, heparin, and low molecular weight heparin (LMWH) all possess significant drawbacks.
Warfarin is typically used to treat patients suffering from atrial fibrillation. The drug interacts with vitamin K—dependent coagulation factors which include factors II, VII, IX and X. Anticoagulant proteins C and S are also inhibited by warfarin. Drug therapy using warfarin is further complicated by the fact that warfarin interacts with other medications, including drugs used to treat atrial fibrillation, such as amiodarone. Because therapy with warfarin is difficult to predict, patients must be carefully monitored in order to detect any signs of anomalous bleeding.
Heparin functions by activating antithrombin which inhibits both thrombin and factor X. (Bjork I, Lindahl U. Mol Cell Biochem. 1982 48: 161-182.) Treatment with heparin may cause an immunological reaction that makes platelets aggregate within blood vessels that can lead to thrombosis. This side effect is known as heparin-induced thrombocytopenia (HIT) and requires patient monitoring. Prolonged treatment with heparin may also lead to osteoporosis. LMWH can also inhibit Factor 2, but to a lesser degree than unfractioned heparin (UFH). LMWH has been implicated in the development of HIT.
Thus, current anticoagulant agents lack predictability and specificity and, therefore, require careful patient monitoring to prevent adverse side effects, such as bleeding complications. There are currently no anticoagulants which target only the intrinsic or extrinsic pathway.

Antisense Compounds
Oligomeric compounds include, but are not limited to, oligonucleotides, oligonucleosides, oligonucleotide analogs, oligonucleotide mimetics, antisense compounds, antisense oligonucleotides, and siRNAs. An oligomeric compound may be “antisense” to a target nucleic acid, meaning that it is capable of undergoing hybridization to a target nucleic acid through hydrogen bonding.
In certain embodiments, an antisense compound has a nucleobase sequence that, when written in the 5′ to 3′ direction, comprises the reverse complement of the target segment of a target nucleic acid to which it is targeted. In certain such embodiments, an antisense oligonucleotide has a nucleobase sequence that, when written in the 5′ to 3′ direction, comprises the reverse complement of the target segment of a target nucleic acid to which it is targeted.
In certain embodiments, an antisense compound targeted to a Factor 7 nucleic acid is 12 to 30 subunits in length. In other words, antisense compounds are from 12 to 30 linked subunits. In other embodiments, the antisense compound is 8 to 80, 12 to 50, 15 to 30, 18 to 24, 19 to 22, or 20 linked subunits. In certain such embodiments, the antisense compounds are 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, or 80 linked subunits in length, or a range defined by any two of the above values. In some embodiments the antisense compound is an antisense oligonucleotide, and the linked subunits are nucleotides.
In certain embodiments, a shortened or truncated antisense compound targeted to a Factor 7 nucleic acid has a single subunit deleted from the 5′ end (5′ truncation), or alternatively from the 3′ end (3′ truncation). A shortened or truncated antisense compound targeted to a Factor 7 nucleic acid may have two subunits deleted from the 5′ end, or alternatively may have two subunits deleted from the 3′ end, of the antisense compound. Alternatively, the deleted nucleosides may be dispersed throughout the antisense compound; for example, in an antisense compound having one nucleoside deleted from the 5′ end and one nucleoside deleted from the 3′ end.
When a single additional subunit is present in a lengthened antisense compound, the additional subunit may be located at the 5′ or 3′ end of the antisense compound. When two or more additional subunits are present, the added subunits may be adjacent to each other; for example, in an antisense compound having two subunits added to the 5′ end (5′ addition), or alternatively to the 3′ end (3′ addition), of the antisense compound. Alternatively, the added subunits may be dispersed throughout the antisense compound, for example, in an antisense compound having one subunit added to the 5′ end and one subunit added to the 3′ end.
It is possible to increase or decrease the length of an antisense compound, such as an antisense oligonucleotide, and/or introduce mismatch bases without eliminating activity. For example, in Woolf et al. (Proc. Natl. Acad. Sci. USA 89:7305-7309, 1992), a series of antisense oligonucleotides 13-25 nucleobases in length were tested for their ability to induce cleavage of a target RNA in an oocyte injection model. Antisense oligonucleotides 25 nucleobases in length with 8 or 11 mismatch bases near the ends of the antisense oligonucleotides were able to direct specific cleavage of the target mRNA, albeit to a lesser extent than the antisense oligonucleotides that contained no mismatches. Similarly, target specific cleavage was achieved using 13 nucleobase antisense oligonucleotides, including those with 1 or 3 mismatches.
Gautschi et al. (J. Natl. Cancer Inst. 93:463-471, March 2001) demonstrated the ability of an oligonucleotide having 100% complementarity to the bcl-2 mRNA and having 3 mismatches to the bcl-xL mRNA to reduce the expression of both bcl-2 and bcl-xL in vitro and in vivo. Furthermore, this oligonucleotide demonstrated potent anti-tumor activity in vivo.
Maher and Dolnick (Nuc. Acid. Res. 16:3341-3358, 1988) tested a series of tandem 14 nucleobase antisense oligonucleotides, and 28 and 42 nucleobase antisense oligonucleotides comprised of the sequence of two or three of the tandem antisense oligonucleotides, respectively, for their ability to arrest translation of human DHFR in a rabbit reticulocyte assay. Each of the three 14 nucleobase antisense oligonucleotides alone was able to inhibit translation, albeit at a more modest level than the 28 or 42 nucleobase antisense oligonucleotides.
Antisense Compound Motifs
In certain embodiments, antisense compounds targeted to a Factor 7 nucleic acid have chemically modified subunits arranged in patterns, or motifs, to confer to the antisense compounds properties, such as enhanced inhibitory activity, increased binding affinity for a target nucleic acid, or resistance to degradation by in vivo nucleases.
Chimeric antisense compounds typically contain at least one region modified so as to confer increased resistance to nuclease degradation, increased cellular uptake, increased binding affinity for the target nucleic acid, and/or increased inhibitory activity. A second region of a chimeric antisense compound may optionally serve as a substrate for the cellular endonuclease RNase H, which cleaves the RNA strand of an RNA:DNA duplex.
Antisense compounds having a gapmer motif are considered chimeric antisense compounds. In a gapmer, an internal region having a plurality of nucleotides that supports RNaseH cleavage is positioned between external regions having a plurality of nucleotides that are chemically distinct from the nucleosides of the internal region. In the case of an antisense oligonucleotide having a gapmer motif, the gap segment supports cleavage of the target nucleic acid, while the wing segments comprise modified nucleosides to enhance stability, affinity, and exonuclease resistance. In certain embodiments, the regions of a gapmer are differentiated by the types of sugar moieties comprising each distinct region. The types of sugar moieties that are used to differentiate the regions of a gapmer may, in some embodiments, include β-D-ribonucleosides, β-D-deoxyribonucleosides, 2′-modified nucleosides (such 2′-modified nucleosides may include 2′-MOE, and 2′-O—CH3, among others), and bicyclic sugar modified nucleosides (such bicyclic sugar modified nucleosides may include those having a 4′-(CH2)n-O-2′ bridge, where n=1 or n=2). Preferably, each distinct region comprises uniform sugar moieties. The wing-gap-wing motif is frequently described as “X-Y-Z”, where “X” represents the length of the 5′ wing region, “Y” represents the length of the gap region, and “Z” represents the length of the 3′ wing region. As used herein, a gapmer described as “X-Y-Z” has a configuration such that the gap segment is positioned immediately adjacent each of the 5′ wing segment and the 3′ wing segment. Thus, no intervening nucleotides exist between the 5′ wing segment and gap segment, or the gap segment and the 3′ wing segment. Any of the antisense compounds described herein can have a gapmer motif. In some embodiments, X and Z are the same, in other embodiments they are different. In a preferred embodiment, Y is between 8 and 15 nucleotides. X, Y or Z can be any of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, or more nucleotides. Thus, gapmers of the present invention include, but are not limited to, for example, 5-10-5, 4-8-4, 4-12-3, 4-12-4, 3-14-3, 2-13-5, 2-16-2, 1-18-1, 3-10-3, 2-10-2, 1-10-1 or 2-8-2.
In certain embodiments, the antisense compound has a “wingmer” motif, having a wing-gap or gap-wing configuration, i.e. an X-Y or Y-Z configuration, as described above, for the gapmer configuration. Thus, wingmer configurations of the present invention include, but are not limited to, for example, 5-10, 8-4, 4-12, 12-4, 3-14, 16-2, 18-1, 10-3, 2-10, 1-10, 8-2, 2-13, or 5-13.
In certain embodiments, antisense compounds targeted to a Factor 7 nucleic acid possess a 5-10-5 gapmer motif.
In certain embodiments, antisense compounds targeted to a Factor 7 nucleic acid possess a 3-14-3 gapmer motif.
In certain embodiments, antisense compounds targeted to a Factor 7 nucleic acid possess a 2-13-5 gapmer motif.
In certain embodiments, antisense compounds targeted to a Factor 7 nucleic acid possess a 2-12-2 gapmer motif

In certain embodiments, a gap-widened antisense oligonucleotide targeted to a Factor 7 nucleic acid has a gap segment of fourteen 2′-deoxyribonucleotides positioned immediately adjacent to and between wing segments of three chemically modified nucleosides. In certain embodiments, the chemical modification comprises a 2′-sugar modification. In another embodiment, the chemical modification comprises a 2′-MOE sugar modification.
In certain embodiments, a gap-widened antisense oligonucleotide targeted to a Factor 7 nucleic acid has a gap segment of thirteen 2′-deoxyribonucleotides positioned immediately adjacent to and between a 5′ wing segment of two chemically modified nucleosides and a 3′ wing segment of five chemically modified nucleosides. In certain embodiments, the chemical modification comprises a 2′-sugar modification. In another embodiment, the chemical modification comprises a 2′-MOE sugar modification.
Target Nucleic Acids, Target Regions and Nucleotide Sequences
Nucleotide sequences that encode the Factor 7 gene sequence include, without limitation, the following: GENBANK® Accession No. NT—027140.6, truncated from 1255000 to 1273000, first deposited with GENBANK® on Jul. 17, 2001, incorporated herein as SEQ ID NO: 1; GENBANK Accession No. NM—019616.2, first deposited with GENBANK® on Oct. 3, 2000, and incorporated herein as SEQ ID NO: 2; GENBANK® Accession No. DB184141.1, first deposited with GENBANK® on Dec. 11, 2005, incorporated herein as SEQ ID NO: 3; GENBANK Accession No. NM—000131.3, first deposited with GENBANK® on Mar. 24, 1999, and incorporated herein as SEQ ID NO: 167; GENBANK Accession No. NT—039455.6, truncated at nucleotides 10024000 to 10037000, first deposited with GENBANK® on Feb. 24, 2003, and incorporated herein as SEQ ID NO: 160; GENBANK Accession No. NW—00104507.1, incorporated herein as SEQ ID NO: 162; and GENBANK Accession No. 3360—061_B, incorporated herein as SEQ ID NO: 163.
It is understood that the sequence set forth in each SEQ ID NO in the Examples contained herein is independent of any modification to a sugar moiety, an internucleoside linkage, or a nucleobase. As such, antisense compounds defined by a SEQ ID NO may comprise, independently, one or more modifications to a sugar moiety, an internucleoside linkage, or a nucleobase. Antisense compounds described by Isis Number (Isis No.) indicate a combination of nucleobase sequence and motif.
In certain embodiments, a target region is a structurally defined region of the target nucleic acid. For example, a target region may encompass a 3′ UTR, a 5′ UTR, an exon, an intron, an exon/intron junction, a coding region, a translation initiation region, a translation termination region, or other defined nucleic acid regions. The structurally defined regions for Factor 7 gene sequences can be obtained by accession number from sequence databases, such as NCBI, and such information is incorporated herein by reference. In certain embodiments, a target region may encompass the sequence from a 5′ target site of one target segment within the target region to a 3′ target site of another target segment within the target region.
Targeting includes determination of at least one target segment to which an antisense compound hybridizes, such that a desired effect occurs. In certain embodiments, the desired effect is a reduction in mRNA target nucleic acid levels. In certain embodiments, the desired effect is reduction of levels of protein encoded by the target nucleic acid or a phenotypic change associated with the target nucleic acid.
A target region may contain one or more target segments. Multiple target segments within a target region may be overlapping. Alternatively, they may be non-overlapping. In certain embodiments, target segments within a target region are separated by no more than about 300 nucleotides. In certain embodiments, target segments within a target region are separated by a number of nucleotides that is, is about, is no more than, is no more than about, 250, 200, 150, 100, 90, 80, 70, 60, 50, 40, 30, 20, or 10 nucleotides on the target nucleic acid, or is a range defined by any two of the preceding values. In certain embodiments, target segments within a target region are separated by no more than, or no more than about, 5 nucleotides on the target nucleic acid. In certain embodiments, target segments are contiguous. Contemplated are target regions defined by a range having a starting nucleic acid that is any of the 5′ target sites or 3′ target sites listed herein.
Suitable target segments may be found within a 5′ UTR, a coding region, a 3′ UTR, an intron, an exon, or an exon/intron junction. Target segments containing a start codon or a stop codon are also suitable target segments. A suitable target segment may specifically exclude a certain structurally defined region, such as the start codon or stop codon.
The determination of suitable target segments may include a comparison of the sequence of a target nucleic acid to other sequences throughout the genome. For example, the BLAST algorithm may be used to identify regions of similarity amongst different nucleic acids. This comparison can prevent the selection of antisense compound sequences that may hybridize in a non-specific manner to sequences other than a selected target nucleic acid (i.e., non-target or off-target sequences).
There may be variation in activity (e.g., as defined by percent reduction of target nucleic acid levels) of the antisense compounds within an active target region. In certain embodiments, reductions in Factor 7 mRNA levels are indicative of inhibition of Factor 7 expression. Reductions in levels of a Factor 7 protein are also indicative of inhibition of target mRNA expression. Further, phenotypic changes are indicative of inhibition of Factor 7 expression. For example, a prolonged PT time can be indicative of inhibition of Factor 7 expression. In another example, prolonged aPTT time in conjunction with a prolonged PT time can be indicative of inhibition of Factor 7 expression. In another example, a decreased level of Platelet Factor 4 (PF-4) expression can be indicative of inhibition of Factor 7 expression. In another example, reduced formation of thrombus or increased time for thrombus formation can be indicative of inhibition of Factor 7 expression.
Hybridization
In some embodiments, hybridization occurs between an antisense compound disclosed herein and a Factor 7 nucleic acid. The most common mechanism of hybridization involves hydrogen bonding (e.g., Watson-Crick, Hoogsteen or reversed Hoogsteen hydrogen bonding) between complementary nucleobases of the nucleic acid molecules.
Hybridization can occur under varying conditions. Stringent conditions are sequence-dependent and are determined by the nature and composition of the nucleic acid molecules to be hybridized.
Methods of determining whether a sequence is specifically hybridizable to a target nucleic acid are well known in the art. In certain embodiments, the antisense compounds provided herein are specifically hybridizable with a Factor 7 nucleic acid.
Complementarity
An antisense compound and a target nucleic acid are complementary to each other when a sufficient number of nucleobases of the antisense compound can hydrogen bond with the corresponding nucleobases of the target nucleic acid, such that a desired effect will occur (e.g., antisense inhibition of a target nucleic acid, such as a Factor 7 nucleic acid).
Non-complementary nucleobases between an antisense compound and a Factor 7 nucleic acid may be tolerated provided that the antisense compound remains able to specifically hybridize to a target nucleic acid. Moreover, an antisense compound may hybridize over one or more segments of a Factor 7 nucleic acid such that intervening or adjacent segments are not involved in the hybridization event (e.g., a loop structure, mismatch or hairpin structure).
In certain embodiments, the antisense compounds provided herein, or a specified portion thereof, are, or are at least, 70%, 80%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% complementary to a Factor 7 nucleic acid, a target region, target segment, or specified portion thereof. Percent complementarity of an antisense compound with a target nucleic acid can be determined using routine methods.
For example, an antisense compound in which 18 of 20 nucleobases of the antisense compound are complementary to a target region, and would therefore specifically hybridize, would represent 90 percent complementarity. In this example, the remaining non-complementary nucleobases may be clustered or interspersed with complementary nucleobases and need not be contiguous to each other or to complementary nucleobases. As such, an antisense compound which is 18 nucleobases in length having 4 (four) non-complementary nucleobases which are flanked by two regions of complete complementarity with the target nucleic acid would have 77.8% overall complementarity with the target nucleic acid and would thus fall within the scope of the present invention. Percent complementarity of an antisense compound with a region of a target nucleic acid can be determined routinely using BLAST programs (basic local alignment search tools) and PowerBLAST programs known in the art (Altschul et al., J. Mol. Biol., 1990, 215, 403 410; Zhang and Madden, Genome Res., 1997, 7, 649 656). Percent homology, sequence identity or complementarity can be determined by, for example, the Gap program (Wisconsin Sequence Analysis Package, Version 8 for Unix, Genetics Computer Group, University Research Park, Madison Wis.), using default settings, which uses the algorithm of Smith and Waterman (Adv. Appl. Math., 1981, 2, 482 489).
In certain embodiments, the antisense compounds provided herein, or specified portions thereof, are fully complementary (i.e. 100% complementary) to a target nucleic acid, or specified portion thereof. For example, antisense compound may be fully complementary to a Factor 7 nucleic acid, or a target region, or a target segment or target sequence thereof. As used herein, “fully complementary” means each nucleobase of an antisense compound is capable of precise base pairing with the corresponding nucleobases of a target nucleic acid. For example, a 20 nucleobase antisense compound is fully complementary to a target sequence that is 400 nucleobases long, so long as there is a corresponding 20 nucleobase portion of the target nucleic acid that is fully complementary to the antisense compound. Fully complementary can also be used in reference to a specified portion of the first and/or the second nucleic acid. For example, a 20 nucleobase portion of a 30 nucleobase antisense compound can be “fully complementary” to a target sequence that is 400 nucleobases long. The 20 nucleobase portion of the 30 nucleobase oligonucleotide is fully complementary to the target sequence if the target sequence has a corresponding 20 nucleobase portion wherein each nucleobase is complementary to each nucleobase of the 20 nucleobase portion of the antisense compound. At the same time, the entire 30 nucleobase antisense compound may or may not be fully complementary to the target sequence, depending on whether the remaining 10 nucleobases of the antisense compound are also complementary to the target sequence.
The location of a non-complementary nucleobase may be at the 5′ end or 3′ end of the antisense compound. Alternatively, the non-complementary nucleobase or nucleobases may be at an internal position of the antisense compound. When two or more non-complementary nucleobases are present, they may be contiguous (i.e. linked) or non-contiguous. In one embodiment, a non-complementary nucleobase is located in the wing segment of a gapmer antisense oligonucleotide.
In certain embodiments, antisense compounds that are, or are up to 12, 13, 14, 15, 16, 17, 18, 19, or 20 nucleobases in length comprise no more than 4, no more than 3, no more than 2, or no more than 1 non-complementary nucleobase(s) relative to a target nucleic acid, such as a Factor 7 nucleic acid, or specified portion thereof.
In certain embodiments, antisense compounds that are, or are up to 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 nucleobases in length comprise no more than 6, no more than 5, no more than 4, no more than 3, no more than 2, or no more than 1 non-complementary nucleobase(s) relative to a target nucleic acid, such as a Factor 7 nucleic acid, or specified portion thereof.
The antisense compounds provided herein also include those which are complementary to a portion of a target nucleic acid. As used herein, “portion” refers to a defined number of contiguous (i.e. linked) nucleobases within a region or segment of a target nucleic acid. A “portion” can also refer to a defined number of contiguous nucleobases of an antisense compound. In certain embodiments, the antisense compounds are complementary to at least an 8 nucleobase portion of a target segment. In certain embodiments, the antisense compounds are complementary to at least a 12 nucleobase portion of a target segment. In certain embodiments, the antisense compounds are complementary to at least a 15 nucleobase portion of a target segment. Also contemplated are antisense compounds that are complementary to at least a 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, or more nucleobase portion of a target segment, or a range defined by any two of these values.
Identity
The antisense compounds provided herein may also have a defined percent identity to a particular nucleotide sequence, SEQ ID NO, or compound represented by a specific Isis number, or portion thereof. As used herein, an antisense compound is identical to the sequence disclosed herein if it has the same nucleobase pairing ability. For example, a RNA, which contains uracil in place of thymidine in a disclosed DNA sequence, would be considered identical to the DNA sequence since both uracil and thymidine pair with adenine. Shortened and lengthened versions of the antisense compounds described herein, as well as compounds having non-identical bases relative to the antisense compounds provided herein, are also contemplated. The non-identical bases may be adjacent to each other or dispersed throughout the antisense compound. Percent identity of an antisense compound is calculated according to the number of bases that have identical base pairing relative to the sequence to which it is being compared.
In certain embodiments, the antisense compounds, or portions thereof, are at least 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% or 100% identical to one or more of the antisense compounds or SEQ ID NOs, or a portion thereof, disclosed herein.
Modifications
A nucleoside is a base-sugar combination. The nucleobase (also known as base) portion of the nucleoside is normally a heterocyclic base moiety. Nucleotides are nucleosides that further include a phosphate group covalently linked to the sugar portion of the nucleoside. For those nucleosides that include a pentofuranosyl sugar, the phosphate group can be linked to the 2′, 3′ or 5′ hydroxyl moiety of the sugar. Oligonucleotides are formed through the covalent linkage of adjacent nucleosides to one another, to form a linear polymeric oligonucleotide. Within the oligonucleotide structure, the phosphate groups are commonly referred to as forming the internucleoside linkages of the oligonucleotide.
Modifications to antisense compounds encompass substitutions or changes to intemucleoside linkages, sugar moieties, or nucleobases. Modified antisense compounds are often preferred over native forms because of desirable properties such as, for example, enhanced cellular uptake, enhanced affinity for nucleic acid target, increased stability in the presence of nucleases, or increased inhibitory activity.
Chemically modified nucleosides may also be employed to increase the binding affinity of a shortened or truncated antisense oligonucleotide for its target nucleic acid. Consequently, comparable results can often be obtained with shorter antisense compounds that have such chemically modified nucleosides.
Modified Internucleoside Linkages
The naturally occurring internucleoside linkage of RNA and DNA is a 3′ to 5′ phosphodiester linkage. Antisense compounds having one or more modified, i.e. non-naturally occurring, internucleoside linkages are often selected over antisense compounds having naturally occurring internucleoside linkages because of desirable properties, such as, for example, enhanced cellular uptake, enhanced affinity for target nucleic acids, and increased stability in the presence of nucleases.
Oligonucleotides having modified internucleoside linkages include internucleoside linkages that retain a phosphorus atom as well as internucleoside linkages that do not have a phosphorus atom. Representative phosphorus containing internucleoside linkages include, but are not limited to, phosphodiesters, phosphotriesters, methylphosphonates, phosphoramidate, and phosphorothioates. Methods of preparation of phosphorous-containing and non-phosphorous-containing linkages are well known.
In certain embodiments, antisense compounds targeted to a Factor 7 nucleic acid comprise one or more modified internucleoside linkages. In certain embodiments, the modified internucleoside linkages are phosphorothioate linkages. In certain embodiments, each internucleoside linkage of an antisense compound is a phosphorothioate internucleoside linkage.
Modified Sugar Moieties
Antisense compounds of the invention can optionally contain one or more nucleosides wherein the sugar group has been modified. Such sugar modified nucleosides may impart enhanced nuclease stability, increased binding affinity or some other beneficial biological property to the antisense compounds. In certain embodiments, nucleosides comprise chemically modified ribofuranose ring moieties. Examples of chemically modified ribofuranose rings include, without limitation, addition of substituent groups (including 5′ and 2′ substituent groups, bridging of non-geminal ring atoms to form bicyclic nucleic acids (BNA), replacement of the ribosyl ring oxygen atom with S, N(R), or C(R1)(R)2 (R═H, C1-C12 alkyl or a protecting group) and combinations thereof. Examples of chemically modified sugars include 2′-F-5′-methyl substituted nucleoside (see PCT International Application WO 2008/101157, published on Aug. 21, 2008, for other disclosed 5′,2′-bis substituted nucleosides) or replacement of the ribosyl ring oxygen atom with ‘S’ and with further substitution at the 2′-position (see U.S. Patent. Application US2005-0130923, published on Jun. 16, 2005) or alternatively 5′-substitution of a BNA (see PCT International Application WO 2007/134181, published on Nov. 22, 2007, wherein LNA is substituted with, for example, a 5′-methyl or a 5′-vinyl group).
Examples of nucleosides having modified sugar moieties include, without limitation, nucleosides comprising 5′-vinyl, 5′-methyl (R or S), 4′-S, 2′-F, 2′-OCH3 and 2′-O(CH2)2OCH3 substituent groups. The substituent at the 2′ position can also be selected from allyl, amino, azido, thio, O-allyl, O—C1-C10 alkyl, OCF3, O(CH2)2SCH3, O(CH2)2—O—N(Rm)(Rn), and O—CH2—C(═O)—N(Rm)(Rn), where each Rm and Rn is, independently, H or substituted or unsubstituted C1-C10 alkyl.
Examples of bicyclic nucleic acids (BNAs) include, without limitation, nucleosides comprising a bridge between the 4′ and the 2′ ribosyl ring atoms. In certain embodiments, antisense compounds provided herein include one or more BNA nucleosides, wherein the bridge comprises one of the formulas: 4′-(CH2)—O-2′ (LNA); 4′-(CH2)—S-2′; 4′-(CH2)—O-2′ (LNA); 4′-(CH2)2—O-2′ (ENA); 4′-C(CH3)2—O-2′ (see PCT/US2008/068922); 4′-CH(CH3)—O-2′ and 4′-C

Each of the foregoing BNAs include various stereochemical sugar configurations, including, for example, α-L-ribofuranose and β-D-ribofuranose (see PCT international application PCT/DK98/00393, published on Mar. 25, 1999 as WO 99/14226).
In certain embodiments, nucleosides are modified by replacement of the ribosyl ring with a sugar surrogate. Such modification includes, without limitation, replacement of the ribosyl ring with a surrogate ring system (sometimes referred to as DNA analogs), such as a morpholino ring, a cyclohexenyl ring, a cyclohexyl ring or a tetrahydropyranyl ring, such as one having one of the formulas:
Many other bicyclo and tricyclo sugar surrogate ring systems are also known in the art that can be used to modify nucleosides for incorporation into antisense compounds (see, for example, review article: Leumann, Christian J.). Such ring systems can undergo various additional substitutions to enhance activity.
Methods for the preparations of modified sugars are well known to those skilled in the art.
In nucleotides having modified sugar moieties, the nucleobase moieties (natural, modified or a combination thereof) are maintained for hybridization with an appropriate nucleic acid target.
In certain embodiments, antisense compounds targeted to a Factor 7 nucleic acid comprise one or more nucleotides having modified sugar moieties. In certain embodiments, the modified sugar moiety is 2′-MOE. In certain embodiments, the 2′-MOE modified nucleotides are arranged in a gapmer motif.
Modified Nucleobases
Nucleobase (or base) modifications or substitutions are structurally distinguishable from, yet functionally interchangeable with, naturally occurring or synthetic unmodified nucleobases. Both natural and modified nucleobases are capable of participating in hydrogen bonding. Such nucleobase modifications may impart nuclease stability, binding affinity or some other beneficial biological property to antisense compounds. Modified nucleobases include synthetic and natural nucleobases such as, for example, 5-methylcytosine (5-me-C). Certain nucleobase substitutions, including 5-methylcytosine substitutions, are particularly useful for increasing the binding affinity of an antisense compound for a target nucleic acid. For example, 5-methylcytosine substitutions have been shown to increase nucleic acid duplex stability by 0.6-1.2° C. (Sanghvi, Y. S., Crooke, S. T. and Lebleu, B., eds., Antisense Research and Applications, CRC Press, Boca Raton, 1993, pp. 276-278).

Compositions and Methods for Formulating Pharmaceutical Compositions
Antisense oligonucleotides may be admixed with pharmaceutically acceptable active or inert substances for the preparation of pharmaceutical compositions or formulations. Compositions and methods for the formulation of pharmaceutical compositions are dependent upon a number of criteria, including, but not limited to, route of administration, extent of disease, or dose to be administered.
Antisense compounds targeted to a Factor 7 nucleic acid can be utilized in pharmaceutical compositions by combining the antisense compound with a suitable pharmaceutically acceptable diluent or carrier. A pharmaceutically acceptable diluent includes phosphate-buffered saline (PBS). PBS is a diluent suitable for use in compositions to be delivered parenterally. Accordingly, in one embodiment employed in the methods described herein is a pharmaceutical composition comprising an antisense compound targeted to a Factor 7 nucleic acid and a pharmaceutically acceptable diluent. In certain embodiments, the pharmaceutically acceptable diluent is PBS. In certain embodiments, the antisense compound is an antisense oligonucleotide.
Pharmaceutical compositions comprising antisense compounds encompass any pharmaceutically acceptable salts, esters, or salts of such esters, or any other oligonucleotide which, upon administration to an animal, including a human, is capable of providing (directly or indirectly) the biologically active metabolite or residue thereof. Accordingly, for example, the disclosure is also drawn to pharmaceutically acceptable salts of antisense compounds, prodrugs, pharmaceutically acceptable salts of such prodrugs, and other bioequivalents. Suitable pharmaceutically acceptable salts include, but are not limited to, sodium and potassium salts.
A prodrug can include the incorporation of additional nucleosides at one or both ends of an antisense compound which are cleaved by endogenous nucleases within the body, to form the active antisense compound.

Antisense compounds can also be modified to have one or more stabilizing groups that are generally attached to one or both termini of antisense compounds to enhance properties such as, for example, nuclease stability. Included in stabilizing groups are cap structures. These terminal modifications protect the antisense compound having terminal nucleic acid from exonuclease degradation, and can help in delivery and/or localization within a cell. The cap can be present at the 5′-terminus (5′-cap), or at the 3′-terminus (3′-cap), or can be present on both termini. Cap structures are well known in the art and include, for example, inverted deoxy abasic caps. Further 3′ and 5′-stabilizing groups that can be used to cap one or both ends of an antisense compound to impart nuclease stability include those disclosed in WO 03/004602, published on Jan. 16, 2003.

Cell types used for such analyses are available from commerical vendors (e.g. American Type Culture Collection, Manassus, Va.; Zen-Bio, Inc., Research Triangle Park, N.C.; Clonetics Corporation, Walkersville, Md.) and cells are cultured according to the vendor's instructions using commercially available reagents (e.g. Invitrogen Life Technologies, Carlsbad, Calif.). Illustrative cell types include HepG2 cells, HepB3 cells, and primary hepatocytes.
In Vitro Testing of Antisense Oligonucleotides
Described herein are methods for treatment of cells with antisense oligonucleotides, which can be modified appropriately for treatment with other antisense compounds.
In general, cells are treated with antisense oligonucleotides when the cells reach approximately 60-80% confluency in culture.
One reagent commonly used to introduce antisense oligonucleotides into cultured cells includes the cationic lipid transfection reagent LIPOFECTIN® (Invitrogen, Carlsbad, Calif.). Antisense oligonucleotides are mixed with LIPOFECTIN® in OPTI-MEM® 1 (Invitrogen, Carlsbad, Calif.) to achieve the desired final concentration of antisense oligonucleotide and a LIPOFECTIN® concentration that typically ranges 2 to 12 ug/mL per 100 nM antisense oligonucleotide.
Another reagent used to introduce antisense oligonucleotides into cultured cells includes LIPOFECTAMINE® (Invitrogen, Carlsbad, Calif.). Antisense oligonucleotide is mixed with LIPOFECTAMINE® in OPTI-MEM® 1 reduced serum medium (Invitrogen, Carlsbad, Calif.) to achieve the desired concentration of antisense oligonucleotide and a LIPOFECTAMINE® concentration that typically ranges 2 to 12 ug/mL per 100 nM antisense oligonucleotide.
Another technique used to introduce antisense oligonucleotides into cultured cells includes electroporation.
Cells are treated with antisense oligonucleotides by routine methods. Cells are typically harvested 16-24 hours after antisense oligonucleotide treatment, at which time RNA or protein levels of target nucleic acids are measured by methods known in the art and described herein. In general, when treatments are performed in multiple replicates, the data are presented as the average of the replicate treatments.
The concentration of antisense oligonucleotide used varies from cell line to cell line. Methods to determine the optimal antisense oligonucleotide concentration for a particular cell line are well known in the art. Antisense oligonucleotides are typically used at concentrations ranging from 1 nM to 300 nM when transfected with LIPOFECTIN®. Antisense oligonucleotides are used at higher concentrations ranging from 625 to 20,000 nM when transfected using electroporation.
RNA Isolation
RNA analysis can be performed on total cellular RNA or poly(A)+ mRNA. Methods of RNA isolation are well known in the art. RNA is prepared using methods well known in the art, for example, using the TRIZOL® Reagent (Invitrogen, Carlsbad, Calif.), according to the manufacturer's recommended protocols.
Analysis of Inhibition of Target Levels or Expression
Inhibition of levels or expression of a Factor 7 nucleic acid can be assayed in a variety of ways known in the art. For example, target nucleic acid levels can be quantitated by, e.g., Northern blot analysis, competitive reverse transcription polymerase chain reaction (RT-PCR), or quantitative real-time RT-PCR. RNA analysis can be performed on total cellular RNA or poly(A)+ mRNA. Methods of RNA isolation are well known in the art. Northern blot analysis is also routine in the art. Real-time RT-PCR can be conveniently accomplished using the commercially available ABI PRISM® 7600, 7700, or 7900 Sequence Detection System, available from PE-Applied Biosystems, Foster City, Calif., and used according to manufacturer's instructions.
Quantitative Real-Time RT-PCR Analysis of Target RNA Levels
Quantitation of target RNA levels may be accomplished by quantitative real-time RT-PCR using the ABI PRISM® 7600, 7700, or 7900 Sequence Detection System (PE-Applied Biosystems, Foster City, Calif.) according to manufacturer's instructions. Methods of real-time RT-PCR are well known in the art.
Prior to real-time PCR, the isolated RNA is subjected to a reverse transcriptase (RT) reaction, which produces complementary DNA (cDNA) that is then used as the substrate for the real-time PCR amplification. The RT and real-time PCR reactions are performed sequentially in the same sample well. RT and real-time PCR reagents are obtained from Invitrogen (Carlsbad, Calif.). RT and real-time-PCR reactions are carried out by methods well known to those skilled in the art.
Gene (or RNA) target quantities obtained by real-time RT-PCR are normalized using either the expression level of a gene whose expression is constant, such as cyclophilin A, or by quantifying total RNA using RIBOGREEN® (Invitrogen, Inc. Carlsbad, Calif.). Cyclophilin A expression is quantified by real-time RT-PCR, by being run simultaneously with the target, multiplexing, or separately. Total RNA is quantified using RIBOGREEN® RNA quantification reagent (Invetrogen, Inc. Eugene, Oreg.). Methods of RNA quantification by RIBOGREEN® are taught in Jones, L. J., et al., (Analytical Biochemistry, 1998, 265, 368-374). A CYTOFLUOR® 4000 instrument (PE Applied Biosystems) is used to measure RIBOGREEN® fluorescence.
Probes and primers are designed to hybridize to a Factor 7 nucleic acid. Methods for designing real-time RT-PCR probes and primers are well known in the art, and may include the use of software such as PRIMER EXPRESS® Software (Applied Biosystems, Foster City, Calif.).
Analysis of Protein Levels
Antisense inhibition of Factor 7 nucleic acids can be assessed by measuring Factor 7 protein levels. Protein levels of Factor 7 can be evaluated or quantitated in a variety of ways well known in the art, such as immunoprecipitation, Western blot analysis (immunoblotting), enzyme-linked immunosorbent assay (ELISA), quantitative protein assays, protein activity assays (for example, caspase activity assays), immunohistochemistry, immunocytochemistry or fluorescence-activated cell sorting (FACS). Antibodies directed to a target can be identified and obtained from a variety of sources, such as the MSRS catalog of antibodies (Aerie Corporation, Birmingham, Miss.), or can be prepared via conventional monoclonal or polyclonal antibody generation methods well known in the art. Antibodies useful for the detection of human and mouse Factor 7 are commercially available.
In Vivo Testing of Antisense Compounds
Antisense compounds, for example, antisense oligonucleotides, are tested in animals to assess their ability to inhibit expression of Factor 7 and produce phenotypic changes, such as, prolonged PT, prolonged aPTT time, decreased quantity of Platelet Factor 4 (PF-4), reduced formation of thrombus or increased time for thrombus formation, and reduction of cellular proliferation. Testing may be performed in normal animals, or in experimental disease models. For administration to animals, antisense oligonucleotides are formulated in a pharmaceutically acceptable diluent, such as phosphate-buffered saline. Administration includes parenteral routes of administration, such as intraperitoneal, intravenous, and subcutaneous. Calculation of antisense oligonucleotide dosage and dosing frequency is within the abilities of those skilled in the art, and depends upon factors such as route of administration and animal body weight. Following a period of treatment with antisense oligonucleotides, RNA is isolated from liver tissue and changes in Factor 7 nucleic acid expression are measured. Changes in Factor 7 protein levels are also measured using a thrombin generation assay. In addition, effects on clot times, e.g. PT and aPTT, are determined using plasma from treated animals.

In certain embodiments, pharmaceutical compositions comprising an antisense compound targeted to Factor 7 are used for the preparation of a medicament for treating a patient suffering or susceptible to a thromboembolic complication.
Certain Combination Therapies
In certain embodiments, one or more pharmaceutical compositions of the present invention are co-administered with one or more other pharmaceutical agents. In certain embodiments, such one or more other pharmaceutical agents are designed to treat the same disease, disorder, or condition as the one or more pharmaceutical compositions of the present invention. In certain embodiments, such one or more other pharmaceutical agents are designed to treat a different disease, disorder, or condition as the one or more pharmaceutical compositions of the present invention. In certain embodiments, such one or more other pharmaceutical agents are designed to treat an undesired side effect of one or more pharmaceutical compositions of the present invention. In certain embodiments, one or more pharmaceutical compositions of the present invention are co-administered with another pharmaceutical agent to treat an undesired effect of that other pharmaceutical agent. In certain embodiments, one or more pharmaceutical compositions of the present invention are co-administered with another pharmaceutical agent to produce a combinational effect. In certain embodiments, one or more pharmaceutical compositions of the present invention are co-administered with another pharmaceutical agent to produce a synergistic effect.
In certain embodiments, one or more pharmaceutical compositions of the present invention and one or more other pharmaceutical agents are administered at the same time. In certain embodiments, one or more pharmaceutical compositions of the present invention and one or more other pharmaceutical agents are administered at different times. In certain embodiments, one or more pharmaceutical compositions of the present invention and one or more other pharmaceutical agents are prepared together in a single formulation. In certain embodiments, one or more pharmaceutical compositions of the present invention and one or more other pharmaceutical agents are prepared separately.
In certain embodiments, pharmaceutical agents that may be co-administered with a pharmaceutical composition of the present invention include anticoagulant or antiplatelet agents. In certain embodiments, pharmaceutical agents that may be co-administered with a pharmaceutical composition of the present invention include, but are not limited to aspirin, clopidogrel, dipyridamole, ticlopidine, warfarin (and related coumarins), heparin, direct thrombin inhibitors (such as lepirudin, bivalirudin), apixaban, lovenox, and small molecular compounds that interfere directly with the enzymatic action of particular coagulation factors (e.g. rivaroxaban, which interferes with Factor Xa). In certain embodiments, the anticoagulant or antiplatelet agent is administered prior to administration of a pharmaceutical composition of the present invention. In certain embodiments, the anticoagulant or antiplatelet agent is administered following administration of a pharmaceutical composition of the present invention. In certain embodiments the anticoagulant or antiplatelet agent is administered at the same time as a pharmaceutical composition of the present invention. In certain embodiments the dose of a co-administered anticoagulant or antiplatelet agent is the same as the dose that would be administered if the anticoagulant or antiplatelet agent was administered alone. In certain embodiments the dose of a co-administered anticoagulant or antiplatelet agent is lower than the dose that would be administered if the anticoagulant or antiplatelet agent was administered alone. In certain embodiments the dose of a co-administered anticoagulant or antiplatelet agent is greater than the dose that would be administered if the anticoagulant or antiplatelet agent was administered alone.
In certain embodiments, the co-administration of a second compound enhances the anticoagulant effect of a first compound, such that co-administration of the compounds results in an anticoagulant effect that is greater than the effect of administering the first compound alone. In other embodiments, the co-administration results in anticoagulant effects that are additive of the effects of the compounds when administered alone. In certain embodiments, the co-administration results in anticoagulant effects that are supra-additive of the effects of the compounds when administered alone. In certain embodiments, the first compound is an antisense compound. In certain embodiments, the second compound is an antisense compound.
In certain embodiments, an antidote is administered anytime after the administration of a Factor 7 specific inhibitor. In certain embodiments, an antidote is administered anytime after the administration of an antisense oligonucleotide targeting Factor 7. In certain embodiments, the antidote is administered minutes, hours, days, weeks, or months after the administration of an antisense compound targeting Factor 7. In certain embodiments, the antidote is a complementary (e.g. a sense strand) to the antisense compound targeting Factor 7. In certain embodiments, the antidote is a Factor 7 or Factor 7a protein. In certain embodiments, the Factor 7 or Factor 7a, protein is a human Factor 7 or human Factor 7a protein.
While certain compounds, compositions and methods described herein have been described with specificity in accordance with certain embodiments, the following examples serve only to illustrate the compounds described herein and are not intended to limit the same. Each of the references recited in the present application is incorporated herein by reference in its entirety.
Antisense oligonucleotides targeted to a Factor 7 nucleic acid were tested for their effects on Factor 7 mRNA in vitro. Cultured HepB3 cells at a density of 4,000 cells per well were transfected using lipofectin reagent with 50 nM antisense oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and Factor 7 mRNA levels were measured by real-time RT-PCR, as described herein. Factor 7 mRNA levels were adjusted according to total RNA content as measured by RIBOGREEN®. Results are presented as percent inhibition of Factor 7, relative to untreated control cells.
The chimeric antisense oligonucleotides in Table 1 were designed as 5-10-5 MOE gapmers. The gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of ten 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising five nucleotides each. Each nucleotide in the 5′ wing segment and each nucleotide in the 3′ wing segment has a 2′-MOE modification. The internucleoside linkages throughout each gapmer are phosphorothioate (P═S) linkages. All cytidine residues throughout each gapmer are 5-methylcytidines. Each gapmer listed in Table 1 is targeted to human gene sequences, SEQ ID NO: 1 (nucleotides 1255000 to 1273000 of GENBANK Accession No. NT—027140.6), SEQ ID NO: 2 (GENBANK Accession No. NM—019616.2), or SEQ ID NO: 3 (GENBANK Accession No. DB184141.1). “Human Target start site” indicates the 5′-most nucleotide to which the gapmer is targeted in the specified human gene sequence. “Human Target stop site” indicates the 3′-most nucleotide to which the gapmer is targeted in the specified human gene sequence.

Several antisense oligonucleotides from Example 1 (see Table 1) exhibiting at least 80% in vitro inhibition of human Factor 7 were tested at various doses in HepB3 cells. Cells were plated at a density of 4,000 cells per well and treated with lipofectin reagent with 3.125 nM, 6.25 nM, 12.5 nM, 25 nM, 50 nM, and 100 nM concentrations of antisense oligonucleotide, as indicated in Table 3. After a treatment period of approximately 16 hours, RNA was isolated from the cells and Factor 7 mRNA levels were measured by real-time RT-PCR, as described herein. Human Factor 7 primer probe set RTS 2927 (forward sequence: GGGACCCTGATCAACACCAT, incorporated herein as SEQ ID NO: 164; reverse sequence: CCAGTTCTTGATTTTGTCGAAACA, incorporated herein as SEQ ID NO: 165; probe sequence: TGGGTGGTCTCCGCGGCCX, incorporated herein as SEQ ID NO: 166) was used to measure mRNA levels. Factor 7 mRNA levels were adjusted according to total RNA content as measured by RIBOGREEN®. Results are presented as percent inhibition of Factor 7, relative to untreated control cells. As illustrated in Table 3, Factor 7 mRNA levels were reduced in a dose-dependent manner.

Antisense oligonucleotides targeted to a Factor 7 nucleic acid were designed and tested for their effects on Factor 7 mRNA in vitro. Certain antisense oligonucleotides from Table 3 were also retested for their effects on Factor 7 mRNA in vitro. Cultured HepB3 cells at a density of 4,000 cells per well were transfected using lipofectin reagent with 50 nM antisense oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and Factor 7 mRNA levels were measured by real-time RT-PCR, as described herein. Human Factor 7 primer probe set RTS 2927 was used to measure mRNA levels. Factor 7 mRNA levels were adjusted according to total RNA content as measured by RIBOGREEN®. Results are presented as percent inhibition of Factor 7, relative to untreated control.
The chimeric antisense oligonucleotides in Table 4 were designed as 5-10-5 MOE gapmers. The gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of ten 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising five nucleotides each. Each nucleotide in the 5′ wing segment and each nucleotide in the 3′ wing segment has a 2′-MOE modification. The internucleoside linkages throughout each gapmer are phosphorothioate (P═S) linkages. All cytidine residues throughout each gapmer are 5-methylcytidines. The first seven listed gapmers in Table 4 are from Table 3 and are designated by an asterisk (*). “Human Target start site” indicates the 5′-most nucleotide to which the gapmer is targeted in the specified human gene sequence. “Human Target stop site” indicates the 3′-most nucleotide to which the gapmer is targeted in the specified human gene sequence. Each gapmer listed in Table 4 is targeted to SEQ ID NO: 1 (nucleotides 1255000 to 1273000 of GENBANK® Accession No. NT—027140.6), SEQ ID NO: 2 (GENBANK® Accession No. NM—019616.2), or SEQ ID NO: 167 (GENBANK® Accession No. NM—000131.3).

Antisense oligonucleotides targeted to a Factor 7 nucleic acid were designed and tested for their effects on Factor 7 mRNA in vitro. Cultured HepB3 cells at a density of 4,000 cells per well were transfected using lipofectin reagent with 50 nM antisense oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and Factor 7 mRNA levels were measured by real-time RT-PCR, as described herein. Human Factor 7 primer probe set RTS 2927 was used to measure mRNA levels. Factor 7 mRNA levels were adjusted according to total RNA content as measured by RIBOGREEN®. Results are presented as percent inhibition of Factor 7, relative to untreated control.
The chimeric antisense oligonucleotides in Table 6 were designed as 5-10-5 MOE, 3-14-3 MOE, and 2-13-5 MOE gapmers. The 5-10-5 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of ten 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising five nucleotides each. The 3-14-3 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of fourteen 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising three nucleotides each. The 2-13-5 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of thirteen 2′-deoxynucleotides. The central gap is flanked on the 5′ end with a wing comprising two nucleotides and on the 3′ end with a wing comprising five nucleotides. For each of the motifs (5-10-5, 3-14-3, and 2-13-5), each nucleotide in the 5′ wing segment and each nucleotide in the 3′ wing segment has a 2′-MOE modification. The internucleoside linkages throughout each gapmer are phosphorothioate (P═S) linkages. All cytidine residues throughout each gapmer are 5-methylcytidines. “Target start site” indicates the 5′-most nucleotide to which the gapmer is targeted. “Target stop site” indicates the 3′-most nucleotide to which the gapmer is targeted. Each gapmer listed in Table 6 is targeted to SEQ ID NO: 1 (nucleotides 1255000 to 1273000 of GENBANK Accession No. NT—027140.6).

Gapmers (from Tables 1 through 6, above) exhibiting in vitro inhibition of Factor 7 were selected and tested at various doses in HepB3 cells. Cells were plated at a density of 4,000 cells per well and transfected using lipofectin reagent with 6.25 nM, 12.5 nM, 25.0 nM, 50.0 nM, and 100.0 nM concentrations of antisense oligonucleotide, as indicated in Table 7. After a treatment period of approximately 16 hours, RNA was isolated from the cells and Factor 7 mRNA levels were measured by real-time RT-PCR, as described herein. Human Factor 7 primer probe set RTS 2927 was used to measure mRNA levels. Factor 7 mRNA levels were adjusted according to total RNA content as measured by RIBOGREEN®. Results are presented as percent inhibition of Factor 7, relative to untreated control cells. As illustrated in Table 7, Factor 7 mRNA levels were reduced in a dose-dependent manner.

Additional gapmers were designed based on the gapmers presented in Table 7. These gapmers were designed by creating gapmers shifted slightly upstream and downstream (i.e. “microwalk”) of the original gapmers from Table 7. Gapmers were also created with various motifs, e.g. 5-10-5 MOE, 3-14-3 MOE, and 2-13-5 MOE. These gapmers were tested in vitro. Cultured HepB3 cells at a density of 4,000 cells per well were transfected using lipofectin reagent with 50 nM antisense oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and Factor 7 mRNA levels were measured by real-time RT-PCR. Factor 7 mRNA levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent inhibition of Factor 7, relative to untreated control cells.
The in vitro inhibition data for the gapmers designed by microwalk was then compared with the in vitro inhibition data for the gapmers from Table 7, as indicated in Tables 8, 9, 10, 11, 12, and 13. The oligonucleotides are displayed according to the region on the human gene sequence to which they map.
The chimeric antisense oligonucleotides in Table 8 were designed as 5-10-5 MOE, 3-14-3 MOE, and 2-13-5 MOE gapmers. The first listed gapmer in Table 8 is the original gapmer (see Table 7) from which the remaining gapmers were designed via microwalk and is designated by an asterisk (*). The 5-10-5 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of ten 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising five nucleotides each. The 3-14-3 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of fourteen 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising three nucleotides each. The 2-13-5 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of thirteen 2′-deoxynucleotides. The central gap is flanked on the 5′ end with a wing comprising two nucleotides and on the 3′ end with a wing comprising five nucleotides. For each of the motifs (5-10-5, 3-14-3, and 2-13-5), each nucleotide in the 5′ wing segment and each nucleotide in the 3′ wing segment has a 2′-MOE modification. The internucleoside linkages throughout each gapmer are phosphorothioate (P═S) linkages. All cytidine residues throughout each gapmer are 5-methylcytidines. “Target start site” indicates the 5′-most nucleotide to which the gapmer is targeted. “Target stop site” indicates the 3′-most nucleotide to which the gapmer is targeted. Each gapmer listed in Table 8 is targeted to SEQ ID NO: 1 (nucleotides 1255000 to 1273000 of GENBANK Accession No. NT—027140.6).
As shown in Table 8, all of the 5-10-5 MOE gapmers, 3-14-3 MOE gapmers, and 2-13-5 MOE gapmers targeted to the target region beginning at target start site 4868 and ending at the target stop site 4899 (i.e. nucleobases 4868-4899) of SEQ ID NO: 1 inhibited Factor 7 mRNA by at least 48%.

The chimeric antisense oligonucleotides in Table 10 were designed as 5-10-5 MOE, 3-14-3 MOE, and 2-13-5 MOE gapmers. The first listed gapmer in Table 10 is the original gapmer (see Table 7) from which the remaining gapmers were designed via microwalk and is designated by an asterisk (*). The 5-10-5 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of 10 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising 5 nucleotides each. The 3-14-3 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of 14 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising 3 nucleotides each. The 2-13-5 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of 13 2′-deoxynucleotides. The central gap is flanked on the 5′ end with a wing comprising 2 nucleotides and on the 3′ end with a wing comprising 5 nucleotides. For each of the motifs (5-10-5, 3-14-3, and 2-13-5), each nucleotide in the 5′ wing segment and each nucleotide in the 3′ wing segment has a 2′-MOE modification. The internucleoside linkages throughout each gapmer are phosphorothioate (P═S) linkages. All cytidine residues throughout each gapmer are 5-methylcytidines. “Target start site” indicates the 5′-most nucleotide to which the gapmer is targeted. “Target stop site” indicates the 3′-most nucleotide to which the gapmer is targeted. Each gapmer listed in Table 10 is targeted to SEQ ID NO: 1 (nucleotides 1255000 to 1273000 of GENBANK Accession No. NT—027140.6).
As shown in Table 10, most of the 5-10-5 MOE gapmers, 3-14-3 MOE gapmers, and 2-13-5 MOE gapmers targeted to the target region beginning at target start site 13760 and ending at the target stop site 13789 (i.e. nucleobases 13760-13789) of SEQ ID NO: 1 inhibited Factor 7 mRNA by at least 30%.
Certain gapmers within the target region (i.e. nucleobases 13760-13789) inhibited Factor 7 mRNA expression by at least 20%, for example, ISIS numbers 416455, 422175, 422252, 422108, 422176, 422253, 422109, 422177, 422254, 422110, 422178, 422255, 422111, 422179, 422256, 422112, 422180, 422257, 422113, 422181, 422258, 422114, 422259, 422115, 422183, 422260, 422116, 422184, 422261, 416456, and 422185.

The chimeric antisense oligonucleotides in Table 12 were designed as 5-10-5 MOE, 3-14-3 MOE, and 2-13-5 MOE gapmers. The first listed gapmer in Table 12 is the original gapmer (see Table 7) from which the remaining gapmers were designed via microwalk and is designated by an asterisk (*). The 5-10-5 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of 10 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising 5 nucleotides each. The 3-14-3 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of 14 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising 3 nucleotides each. The 2-13-5 gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of 13 2′-deoxynucleotides. The central gap is flanked on the 5′ end with a wing comprising 2 nucleotides and on the 3′ end with a wing comprising 5 nucleotides. For each of the motifs (5-10-5, 3-14-3, and 2-13-5), each nucleotide in the 5′ wing segment and each nucleotide in the 3′ wing segment has a 2′-MOE modification. The internucleoside linkages throughout each gapmer are phosphorothioate (P═S) linkages. All cytidine residues throughout each gapmer are 5-methylcytidines. “Target start site” indicates the 5′-most nucleotide to which the gapmer is targeted. “Target stop site” indicates the 3′-most nucleotide to which the gapmer is targeted. Each gapmer listed in Table 12 is targeted to SEQ ID NO: 1 (nucleotides 1255000 to 1273000 of GENBANK Accession No. NT—027140.6).

Gapmers from Examples 5 and 6 (see Tables 7, 8, 9, 10, 11, 12, and 13), exhibiting in vitro inhibition of human Factor 7, were tested at various doses in HepB3 cells. Cells were plated at a density of 4,000 cells per well and transfected using lipofectin reagent with 3.125 nM, 6.25 nM, 12.5 nM, 25 nM, 50 nM, and 100 nM concentrations of antisense oligonucleotide, as specified in Table 14. After a treatment period of approximately 16 hours, RNA was isolated from the cells and Factor 7 mRNA levels were measured by quantitative real-time PCR. Human Factor 7 primer probe set RTS 2927 was used to measure mRNA levels. Factor 7 mRNA levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent inhibition of Factor 7, relative to untreated control cells. As illustrated in Table 14, Factor 7 mRNA levels were reduced in a dose-dependent manner.

After a treatment period of approximately 16 hours, RNA was isolated from the cells and Factor 7 mRNA levels were measured by quantitative real-time PCR. Human Factor 7 primer probe set RTS 2927 was used to measure mRNA levels. Factor 7 mRNA levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent inhibition of Factor 7, relative to untreated control cells. As illustrated in Table 15, Factor 7 mRNA levels were reduced in a dose-dependent manner.

Gapmers exhibiting in vitro inhibition of human Factor 7 in Example 7 were selected and tested at various doses in HepB3 cells. Cells were plated at a density of 20,000 cells per well and transfected via electroporation with 3.125 μM, 6.25 μM, 12.5 μM, 25 μM, 50 μM, and 100 μM concentrations of antisense oligonucleotide, as specified in Table 16. After a treatment period of approximately 16 hours, RNA was isolated from the cells and human Factor 7 mRNA levels were measured by quantitative real-time PCR. Human Factor 7 primer probe set RTS 2927 was used to measure mRNA levels. Factor 7 mRNA levels were adjusted according to total RNA content, as measured by RIBOGREEN®.

Short antisense oligonucleotides (shortmers) were designed to target a Factor 7 nucleic acid. The shortmers in Table 17 were designed as 2-10-2 MOE gapmers. The gapmers are 14 nucleotides in length, wherein the central gap segment is comprised of 10 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising 2 nucleotides each. Each nucleotide in the 5′ wing segment and each nucleotide in the 3′ wing segment has a 2′-MOE modification. The internucleoside linkages throughout each gapmer are phosphorothioate (P═S) linkages. All cytidine residues throughout each gapmer are 5-methylcytidines.
Shortmers were evaluated for their ability to reduce human Factor 7 mRNA in HepB3 cells and compared with one 5-10-5 chimeric oligonucleotide from Table 16, ISIS 407939. HepB3 cells at a density of 20,000 cells per well in a 96-well plate were transfected using electroporation with 1,000 nM of antisense oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and Factor 7 mRNA levels were measured by real-time RT-PCR, as described herein. Factor 7 mRNA levels were adjusted according to total RNA content as measured by RIBOGREEN®. Results are presented in Table 17 as percent inhibition of Factor 7 mRNA, relative to untreated control cells. ISIS 407939 is the first oligonucleotide in Table 17 to which the shortmers were compared, and is marked by an asterisk (*).
Each gapmer listed in Table 17 is targeted to human gene sequences, SEQ ID NO: 1 (nucleotides 1255000 to 1273000 of GENBANK Accession No. NT—027140.6) or SEQ ID NO: 2 (GENBANK Accession No. NM—019616.2). “Target start site” indicates the 5′-most nucleotide to which the gapmer is targeted in the human gene sequence. “Target stop site” indicates the 3′-most nucleotide to which the gapmer is targeted in the human gene sequence.

Chimeric antisense oligonucleotides were designed as 5-10-5 MOE wings and deoxy gap were designed to target murine Factor 7 (nucleotides 10024000 to 10037000 of GENBANK Accession No. NT—039455.6; incorporated herein as SEQ ID NO: 160). The gapmers are 20 nucleotides in length, wherein the central gap segment is comprised of 10 2′-deoxynucleotides and is flanked on both sides (in the 5′ and 3′ directions) by wings comprising 5 nucleotides each. Each nucleotide in each wing segment has a 2′-MOE modification. The internucleoside linkages throughout each gapmer are phosphorothioate (P═S) linkages. All cytidine residues throughout each gapmer are 5′methylcytidines. The antisense oligonucleotides were evaluated for their ability to reduce murine Factor 7 mRNA in primary mouse hepatocytes. The antisense oligonucleotides were evaluated for their ability to reduce Factor 7 mRNA in primary mouse hepatocytes.
Primary mouse hepatocytes were treated with 6.25 nM, 12.5 nM, 25 nM, 50 nM, 100 nM, and 200 nM of antisense oligonucleotides for a period of approximately 24 hours. RNA was isolated from the cells and Factor 7 mRNA levels were measured by quantitative real-time PCR, as described herein. Murine Factor 7 primer probe set RTS 2855 (forward sequence AATGAGGAACAGTGCTCCTTTGA, SEQ ID NO: 612; reverse sequence TGTAAACAATCCAGAACTGCTTGGT, SEQ ID NO: 613; probe sequence CCCGGGAGATCTTCAAGAGCCCX, SEQ ID NO: 614) was used to measure mRNA levels. Factor 7 mRNA levels were adjusted according to total RNA content as measured by RIBOGREEN®. Certain murine antisense oligonucleotides reduced Factor 7 mRNA levels in a dose-dependent manner.
Four antisense oligonucleotides showing significant dose-dependent inhibition from the in vitro study (see Example 10) were evaluated for their ability to reduce Factor 7 mRNA in vivo. The antisense oligonucleotides are targeted to murine Factor 7 mRNA (nucleotides 10024000 to 10037000 of GENBANK Accession No. NT—039455.6; SEQ ID NO: 160). Target start sites for the four of the antisense oligonucleotides are as follows: 11326, 11336, 11613, and 11766.
Treatment
BALB/c mice were treated with ISIS 403102 (CCATAGAACAGCTTCACAGG, target site 11336, incorporated herein as SEQ ID NO: 161). BALB/c mice were injected subcutaneously with 5 mg/kg, 10 mg/kg, 25 mg/kg, or 50 mg/kg of ISIS 403102 twice a week for 3 weeks. A control group of mice was injected subcutaneously with PBS twice a week for 3 weeks. After the treatment period, whole liver was collected for RNA and protein analysis, and plasma was collected for clotting analysis (PT/aPTT).
RNA Analysis
RNA was extracted from liver tissue for real-time RT-PCR analysis of Factor 7. As shown in Table 18, ISIS 403102 achieved a dose-dependent reduction of murine Factor 7 over the PBS control. Results are presented as percent inhibition of Factor 7, relative to the control.

Protein Analysis

Clotting Analysis
Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) were measured using platelet poor plasma (PPP) from mice treated with ISIS 403102. PT and aPTT values provided in Table 20 are reported as International Normalized Ratio (INR) values. INR values for PT and aPTT were determined by dividing the PT or aPTT value for the experimental group by the PT or aPTT for the PBS treated group. This ratio was then raised to the power of the International Sensitivity Index (ISI) of the tissue factor used. As shown in Table 20, PT was significantly prolonged in mice treated with ISIS 403102 compared to the control. aPTT was slightly prolonged in mice treated with ISIS 403102. These data suggest that ISIS 403102 has a greater affect on the extrinsic pathway of blood coagulation than the intrinsic pathway of blood coagulation.

Treatment
The half-life and duration of action of ISIS 403102 in mice was evaluated. A group of 27 BALB/c mice was injected with 50 mg/kg of ISIS 403102. Three mice from the group were sacrificed at days 1, 2, 3, 4, 6, 8, 12, 24, and 56 after the single dose of ISIS 403102 was administered. A control group of 3 mice was injected with a single dose of PBS, and mice in this group were sacrificed on day 1. Mice in all groups were sacrificed by cervical dislocation following anesthesia with 150 mg/kg ketamine mixed with 10 mg/kg xylazine administered by intraperitoneal injection. Liver was harvested for RNA analysis and plasma was collected for clotting analysis (PT and aPTT).
RNA Analysis
RNA was extracted from liver tissue for real-time RT-PCR analysis of Factor 7. Results are presented as percent inhibition of Factor 7, relative to PBS control. As shown in Table 21, treatment with ISIS 403102 resulted in 92% inhibition of Factor 7 mRNA by day 4 after which the effect of ISIS 403102 gradually decreased and was reduced to 11% by day 24. By day 56, Factor 7 mRNA levels in ISIS 403102 treated mice are equal to that of the PBS control. Results are presented as percent inhibition of Factor 7, relative to control. These data show that the peak effect of a single dose of 50 mg/kg of ISIS 403102 occurs on about day 4 and duration of action lasts for at least 24 days.

PT and aPTT Assay
Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) were measured using platelet poor plasma (PPP) from mice treated with ISIS 403102. PT and aPTT values provided in Table 22 are reported as International Normalized Ratio (INR) values. INR values for PT and aPTT were determined by dividing the PT or aPTT value for the experimental group (i.e. 50 mg/kg treatment with ISIS 403102) by the PT or aPTT for the PBS treated group. This ratio was then raised to the power of the International Sensitivity Index (ISI) of the tissue factor used.
As shown in Table 22, PT increased from 1.11 on day 1 to 1.97 on day 4. PT decreased gradually after day 4 until PT reached 1.10 on day 56. aPTT increased from 1.00 to 1.24 on day 4. aPTT decreased gradually after day 4 until aPTT reached 0.97 on day 56. Consistent with the mRNA expression data (above), these data show that the peak effect of a single dose of 50 mg/kg of ISIS 403102 occurs on about day 4 and duration of action lasts at least 24 days.

Treatment
The duration of action of multiple doses of ISIS 403102 on antisense inhibition of murine Factor 7 and clotting time was evaluated. In a first group of mice, 25 mg/kg of ISIS 403102 was injected subcutaneously as a single dose. Mice from the first group were sacrificed on days 1 and 3 after the single dose. In a second group of mice, 25 mg/kg of ISIS 403102 was administered subcutaneously twice a week for 1 week. Mice from the second group were sacrificed on day 3 after the last dose of ISIS 403102 was administered. In a third group of mice, 25 mg/kg of ISIS 403102 was administered subcutaneously twice a week for 2 weeks. Mice from the third group were sacrificed on day 3 after the last dose of ISIS 403102 was administered. In a fourth group of mice, 25 mg/kg of ISIS 403102 was administered subcutaneously twice a week for 3 weeks. Mice from the fourth group were sacrificed on days 2, 7, 14, 28, 42, and 56 after the last dose of ISIS 403102 was administered. A control group of 3 mice was injected with PBS in a single dose. Mice from the control group were sacrificed 1 day later. Mice in all groups were sacrificed by cervical dislocation following anesthesia with 150 mg/kg ketamine mixed with 10 mg/kg xylazine administered by intraperitoneal injection. Liver was harvested for RNA analysis and plasma was collected for clotting analysis (PT and aPTT) for mice in all groups.
RNA Analysis
RNA was extracted from liver tissue for quantitative RT-PCR analysis of Factor 7. Results are presented as percent inhibition of Factor 7, relative to PBS control. As shown in Table 23, a single dose treatment of ISIS 403102 resulted in inhibition of Factor 7 as early as day 1. Inhibition increased through day 3 in the single dose treatment group. Two doses of ISIS 403102 resulted in increased inhibition on day 3 as compared to one dose of ISIS 403102. Inhibition increased through day 3 in the 2 dose treatment group. Four doses of ISIS 403102 resulted in increased inhibition in comparison to the 2 dose treatment group on day 3.
Six doses of ISIS 403102 resulted in increased inhibition on day 7 as compared to 6 doses of ISIS 403102 on day 2. In mice treated with 6 doses of ISIS 403102, Factor 7 inhibition declined progressively on days 14, 28, 42, and 56.

PT and aPTT Assay
Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) were measured using platelet poor plasma (PPP) from mice treated with ISIS 403102. PT and aPTT values provided in Table 24 are reported as International Normalized Ratio (INR) values. INR values for PT and aPTT were determined by dividing the PT or aPTT value for the experimental group (i.e. 50 mg/kg treatment with ISIS 403102) by the PT or aPTT for the PBS treated group. This ratio was then raised to the power of the International Sensitivity Index (ISI) of the tissue factor used.
As shown in Table 24, PT was increased on day 3 in mice treated with a single dose of ISIS 403102 in comparison to mice treated with a single dose of ISIS 403102 on day 1. On day 3, PT increased in mice treated with 2 doses of ISIS 403102 over mice treated with a single dose of ISIS 403102. PT increased in mice treated with 4 doses of ISIS 403102 over those mice treated with 2 doses of ISIS 403102 on day 3. PT decreased in mice receiving 6 doses of ISIS 403102 from day 7 to day 56.
aPTT was slightly increased on day 3 in mice treated with a single dose of ISIS 403102 in comparison to mice treated with a single dose of ISIS 403102 on day 1. On day 3, aPTT increased in mice treated with 2 doses of ISIS 403102 over mice treated with a single dose of ISIS 403102. aPTT increased in mice treated with 4 doses of ISIS 403102 over those mice treated with 2 doses of ISIS 403102 on day 3. aPTT decreased in mice receiving 6 doses of ISIS 403102 from day 7 to day 56.

Treatment
Three groups of BALB/c mice were injected with 25 mg/kg, 37.5 mg/kg, or 50 mg/kg of ISIS 403102, administered subcutaneously twice a week for 3 weeks. Two control groups of BALB/c mice were treated with PBS, administered subcutaneously twice a week for 3 weeks. Thrombus formation was induced with FeCl3 in half of the mice while the rest of the mice were assayed for tail bleeding. Two days after receiving the last dose of ISIS 403102 or PBS, mice were anesthetized with 150 mg/kg ketamine mixed with 10 mg/kg xylazine administered by intraperitoneal injection. Thrombus formation was induced with FeCl3 in all groups of the VT mice except the first control group.
In mice undergoing FeCl3 treatment, thrombus formation was induced by applying a piece of filter paper (2×4 mm) pre-saturated with 10% FeCl3 solution directly on the vena cava. After 3 minutes of exposure, the filter paper was removed. Thirty minutes after the filter paper application, a fixed length of the vein containing the thrombus was dissected out for platelet analysis. Liver was collected for RNA analysis.
RNA Analysis
RNA was extracted from liver tissue for real-time RT-PCR analysis of Factor 7. Results are presented as percent inhibition of Factor 7, relative to PBS control. As shown in Table 25, treatment with ISIS 403102 resulted in significant dose-dependent reduction of Factor 7 mRNA in comparison to the PBS control. These data show that antisense oligonucleotides can be used to inhibit expression of Factor 7.

Quantification of Platelet Composition
Real-time RT-PCR quantification of platelet factor-4 (PF-4) was used to quantify platelets in the vena cava as a measure of thrombus formation. Results are presented as a percentage of PF-4 in ISIS 403102, as compared to the two PBS-treated control groups. As shown in Table 26, treatment with ISIS 403102 resulted in a reduction of PF-4 in comparison to the PBS control. Therefore, antisense oligonucleotides are useful for inhibiting thrombus and clot formation.

Tail Bleeding Assay
Mice not receiving treatment with FeCl3 solution were evaluated in a tail bleeding chamber. Mice were placed into the bleeding chamber two days after the final treatment of ISIS 403102 or PBS. Mice were anesthetized in the chamber with isofluorane and a small piece of tail (approximately 4 mm from the tip) was cut with sterile scissors. The cut tail was immediately placed in a 15 mL Falcon tube filled with approximately 10 mL of 0.9% NaCl buffer solution warmed to 37° C. The blood was collected over the course of 40 minutes. The saline filled tubes were weighed both before and after bleeding. The results are provided in Table 27.
Treatment with 25 mg/kg and 37.5 mg/kg ISIS 403102 caused a slight decrease in the amount of bleeding in comparison to PBS treated mice. Bleeding was the same in mice treated with 50 mg/kg ISIS 403102 and mice treated with PBS. These data suggest that treatment with ISIS 403102 does not increase hemorrhagic potential.

Treatment
ISIS 403102 and warfarin (Coumadin®) were evaluated in BALB/c mice. Four groups of BALB/c mice were treated with 5 mg/kg, 10 mg/kg, 20 mg/kg, or 40 mg/kg of ISIS 403102, administered subcutaneously twice a week for 3 weeks. Two days after receiving the last dose of ISIS 403102, mice were anesthetized with 150 mg/kg ketamine mixed with 10 mg/kg xylazine administered by intraperitoneal injection. A fifth group of BALB/c mice was treated with 3 mg/kg of warfarin, administered intraperioneally daily for 6 days. Four hours after the last dose of warfarin, mice were sacrificed. A control group of BALB/c mice were treated with PBS, administered subcutaneously twice a week for 3 weeks. Two days after the last dose of PBS, mice were anesthetized with 150 mg/kg ketamine mixed with 10 mg/kg xylazine administered by intraperitoneal injection. Thrombus formation was induced with FeCl3 in groups of mice except the first control group.
In mice undergoing FeCl3 treatment, thrombus formation was induced by applying a piece of filter paper (2×4 mm) pre-saturated with 10% FeCl3 solution directly on the vena cava. After 3 minutes of exposure, the filter paper was removed. Thirty minutes after the filter paper application, a fixed length of the vein containing the thrombus was dissected out for platelet analysis. Liver was collected for RNA analysis.
RNA Analysis
RNA was extracted from liver tissue for real-time RT-PCR analysis of Factor 7. Results are presented as percent inhibition of Factor 7, relative to PBS control. As shown in Table 28, treatment with ISIS 403102 resulted in significant dose-dependent reduction of Factor 7 mRNA in comparison to the PBS control. Conversely, treatment with warfarin did not result in significant reduction of Factor 7 as compared to the PBS control.

Four groups of BALB/c mice were treated with 5 mg/kg, 10 mg/kg, 20 mg/kg, or 40 mg/kg of ISIS 403102, administered subcutaneously twice a week for 3 weeks. Two days after receiving the last dose of ISIS 403102, mice were anesthetized with 150 mg/kg ketamine mixed with 10 mg/kg xylazine administered by intraperitoneal injection. Six additional groups of BALB/c mice was treated with 0.5 mg/kg, 1 mg/kg, 2 mg·kg, 3 mg/kg, 4 mg/kg, or 5 mg/kg of warfarin, administered intraperioneally daily for 6 days. Four hours after the last dose of warfarin, mice were sacrificed. A control group of BALB/c mice were treated with PBS, administered subcutaneously twice a week for 3 weeks. Two days after the last dose of PBS, mice were anesthetized with 150 mg/kg ketamine mixed with 10 mg/kg xylazine administered by intraperitoneal injection. Thrombus formation was induced with FeCl3 in groups of mice except the first control group.

Results are presented as a percentage of PF-4 in ISIS 403102 or warfarin treated mice, as compared to the two PBS-treated control groups. As shown in Table 29, treatment with ISIS 403102 resulted in a dose-dependent reduction of PF-4 in comparison to the PBS control for dosages of 5 mg/kg and higher. Treatment with warfarin resulted in a reduction of PF-4 in comparison to the PBS control at a dose of 1 mg/kg and higher. Therefore, ISIS antisense oligonucleotides are useful for inhibiting thrombus and clot formation.

Treatment
Tail-bleeding was measured to observe whether treatment with ISIS 403102 or warfarin causes internal hemorrhage in mice. ISIS 403102 and warfarin (Coumadin®) were evaluated in the tail bleeding assay. Six groups of BALB/c mice were treated with 1.25 mg/kg, 2.5 mg/kg, 5 mg/kg, 10 mg/kg, 20 mg/kg, or 40 mg/kg of ISIS 403102, administered subcutaneously twice a week for 3 weeks. An additional 6 groups of BALB/c mice were treated with 0.5 mg/kg, 1 mg/kg, 2 mg/kg, 3 mg/kg, 4 mg/kg, and 5 mg/kg of warfarin, administered intraperioneally daily for 6 days. A separate control group of BALB/c mice was treated with PBS, administered subcutaneously twice a week for 3 weeks.
Tail-Bleeding Assay
Two days after the final treatment of ISIS 403102, warfarin, or PBS, mice were placed in a tail bleeding chamber. Mice were anesthetized in the chamber with isofluorane and a small piece of tail (approximately 4 mm from the tip) was cut with sterile scissors. The cut tail was immediately placed in a 15 mL Falcon tube filled with approximately 10 mL of 0.9% NaCl buffer solution warmed to 37° C. The blood was collected over the course of 40 minutes. The saline filled tubes were weighed both before and after bleeding. The results are provided in Table 30.
Treatment with ISIS 403102 did not significantly affect bleeding as compared to PBS control mice. However, warfarin did increase bleeding in mice as compared to the PBS control mice. Increased doses of warfarin correlated positively with increased blood loss. These data suggest that the hemorrhagic potential of ISIS 403102 is low, especially in comparison to warfarin.

Treatment
ISIS 403102 and Apixaban were evaluated in BALB/c mice. In a first group of BALB/c mice, 40 mg/kg of ISIS 403102 was administered subcutaneously twice a week for 3 weeks. An additional 3 groups of BALB/c mice were treated with 5 mg/kg and 10 mg/kg of Apixaban, administered in a single intraperitoneal dose, and 10 mg/kg of Apixaban administered as a single subcutaneous dose. A control group of BALB/c mice was treated with PBS, administered subcutaneously twice a week for 3 weeks.
Tail-Bleeding Assay
Two days after the final treatment of ISIS 403102 or PBS, mice were placed in a tail bleeding chamber. Mice from the groups treated with Apixaban were analyzed 30 minutes after the single dose. Mice were anesthetized in the chamber with isofluorane and a small piece of tail (approximately 4 mm from the tip) was cut with sterile scissors. The cut tail was immediately placed in a 15 mL Falcon tube filled with approximately 10 mL of 0.9% NaCl buffer solution warmed to 37° C. The blood was collected over the course of 40 minutes. The saline filled tubes were weighed before and after bleeding. The results are provided in Table 31.
Mice treated with ISIS 403102 had less bleeding than PBS treated mice. Mice treated with 5 mg/kg of apixaban by intraperitoneal injection had the same amount of bleeding as PBS treated mice. Mice treated with 10 mg/kg of apixaban by intraperitoneal injection had increased bleeding as compared to the PBS treated mice. Mice treated with 10 mg/kg of apixaban by subcutaneous injection had less bleeding than PBS mice. These data suggest that the hemorrhagic potential of ISIS 403102 is low.

The effect of inhibition of Factor 7 with ISIS 403102 on the formation of tissue factor-Factor 7 complex and its role in extravasation of cancer cells during metastasis will be evaluated. Two groups of severe combined immunodeficiency (SCID) mice will be treated with ISIS 403102, injected at a dose of 20 mg/kg twice a week for 3 weeks. A control group of mice will be injected with PBS twice a week for 3 weeks. Two days after the last dose of ISIS 403102 or PBS, one of the ISIS 403102 treated groups and the control group will be injected intravenously with 50×106 MDA-MB-231 breast carcinoma cells.
Two weeks after the injection with MDA-MB-231 breast carcinoma cells, mice will be sacrificed. The lungs will be harvested and real-time RT-PCR analysis of human GAPDH mRNA levels performed. The results will be normalized with mouse cyclophilin A mRNA levels. Human GAPDH levels will in the group treated with ISIS 403102 and MDA-MB-231 breast carcinoma cells group will be compared to human GAPDH levels in the other two groups of mice. This experiment is designed to assess the effect of inhibition of Factor 7 on the development of metastasis in the lungs.
The effect of inhibition of Factor 7 with ISIS 403102 on experimental liver fibrosis will be evaluated in the carbon tetrachloride liver injury model.
Treatment
In a first group of BALB/c mice, 20 mg/kg ISIS 403102 will be injected subcutaneously twice a week for 8 weeks. In a second group of mice, PBS will be injected subcutaneously twice a week for 8 weeks. Two weeks after the first treatment with ISIS 403102 or PBS, both groups of mice will be dosed intraperitoneally with 5 μl of carbon tetrachloride (CCl4) dissolved in 95 μl of mineral oil twice a week for 5 weeks. A third group of mice will be injected with 100 μl mineral oil alone. Mice will be sacrificed by cervical dislocation following anesthesia with isofluorane. Liver tissue will be harvested from all mice. Real-time RT-PCR will be used to determine the expression of fibrosis related genes, including, collagen type 1, α-smooth muscle actin, matrix metalloproteinase (MMP) 3, TGF-β, Timp1 and Timp2 (MMP inhibitors). The levels in the experimental group will be compared to the levels in the control mice to assess the effect of inhibition of Factor 7 on the development of liver fibrosis.
The effect of inhibition of Factor 7 with ISIS 403102 on the formation of tissue factor-Factor 7 complex and its role in fibrin accumulation in the joints leading to joint inflammation and rheumatoid arthritis will be evaluated in a collagen-induced arthritis model.
Treatment
In a first group of DBA/1J mice, 20 mg/kg of ISIS 403102 will be injected subcutaneously twice a week for 8 weeks. Two groups of mice will be injected with PBS twice a week for 8 weeks. Two weeks after the first treatment of ISIS 403102, type II bovine collagen (Chondrex) will be mixed with complete Freund's adjuvant, homogenized on ice and the emulsion, containing 100 μg of collagen, will be injected subcutaneously in the experimental group and the first control group. A booster injection containing 100 μg collagen type II in incomplete Freund's adjuvant will be injected subcutaneously 7 days after the first collagen injection in both these groups.
Mice in all groups will be examined each day from day 18 after the first collagen injection for the visual appearance of arthritis in peripheral joints. The clinical severity of arthritis will be scored as follows: 1 point for each swollen digit except the thumb (maximum, 4), 1 point for the tarsal or carpal joint, and 1 point for the metatarsal or metacarpal joint with a maximum score of 6 for a hindpaw and 5 for a forepaw. Each paw will be graded individually, the cumulative clinical arthritic score per mouse reaching a maximum of 22 points. Arthritis in the experimental groups will be compared to the control group to assess the effect of inhibition of Factor 7 on the development of arthritis in the joints.
Six weeks after the initial injection of collagen, the maximal level of arthritis will be induced. After mice are anesthetized with isofluorane and plasma is collected, the mice will be sacrificed by cervical dislocation. Livers will be harvested for RNA analysis of Factor 7 mRNA. Plasma collected from all three groups will be analyzed for clotting time (PT and aPTT). The measurement of thrombin-antithrombin (TAT) complexes in the plasma will also be performed by ELISA. The results in the experimental groups will be compared to the control group to assess the effect of inhibition of Factor 7 on the clotting time and formation of TAT complexes.
